Jurassic Park III is the second best film in the franchise, behind only the first one. This film is aware that it’s meant to not be taken as seriously, and is a fun ride from start to finish.
I don’t consider III as one of the best movies in the franchise (I’ve only seen the first four, so that’s where my knowledge lies), but I still thought it was a lot of fun, and of the original three JP films, I thought it was the better sequel. III wasn’t boring to watch, it had a good sense of self-awareness, and it tried to capture the magic and wonder of the first movie, which was one of the biggest mistakes The Lost World made.
